proc: enclose desc variable of show_stat() in CONFIG_SPARSE_IRQ
Impact: restructure code to fix compiler warning commit 240d367b4e6c6e3c5075e034db14dba60a6f5fa7 moved desc usage point into #ifdef CONFIG_SPARSE_IRQ. Eliminate the desc variable, otherwise following warning happens: fs/proc/stat.c: In function 'show_stat': fs/proc/stat.c:31: warning: unused variable 'desc' [ akpm: cleaned up the patch to remove #ifdef ] Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
